Description
The Cyrix 486DLC is pin compatible to the Intel i386DX. While the internals of the 486DLC are roughly equivalent to those in the i486SX, the bus interface is identical to that of the Intel 386DX, respectively to allow easy replacement of the Intel CPUs by the Cyrix chips. The overall execution speed is about same as with an i486SX, but if you add a matching Cyrix FPU, e.g. a Cyrix 83D87, the speed is about 50% faster than an i486DX running at the same frequency.
